Changing the head and face of a manager for non-fired teams (e.g. Juventus)


Club Supporter
Hi, help. I would like to change the head and face of a manager like I did in FIFA 21, but I noticed that in Fifa 22 there is something different.
If I want to change the face of Max Allegri of Juventus, in the Squads file (with RDBM program), in the "manager" folder I cannot find Juventus (ID 114153), instead in the DB (using Editor Tool) in the "manager" folder of fifa_ng_db, I find the Juventus ID.
What can I do? Do I need to modify Max Allegri from the DB, create a mod? Can't change manager from RDBM?
